Next Stop: Restructuring?: A Nonparametric Efficiency Analysis of German Public Transport Companies

Hirschhausen, Christian von; Cullmann, Astrid - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2008

In this paper, we present a nonparametric comparative efficiency analysis of 179 communal public transport bus companies in Germany (1990-2004). We apply both deterministic data envelopment analysis (DEA) and bootstrapping to test the robustness of our estimates and to test the hypothesis of...

Potential Gains from Mergers in Local Public Transport: An Efficiency Analysis Applied to Germany

Walter, Matthias; Cullmann, Astrid - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2008

We analyze potential gains from hypothetical mergers in local public transport using the non-parametric Data Envelopment Analysis with bias corrections by means of bootstrapping. Our sample consists of 41 public transport companies from Germany's most densely populated region, North...

Innovation, R&D Efficiency and the Impact of the Regulatory Environment: A Two-Stage Semi-Parametric DEA Approach

Cullmann, Astrid; Schmidt-Ehmcke, Jens; Zloczysti, Petra - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

This paper assesses the relative efficiency of knowledge production in the OECD using a nonparametric DEA approach. Resources allocated to R&D are limited and should therefore be used efficiently given the institutional and legal constraints. This paper presents efficiency scores based on an...

Overcoming Data Limitations in Nonparametric Benchmarking: Applying PCA-DEA to Natural Gas Transmission

Nieswand, Maria; Cullmann, Astrid; Neumann, Anne - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

This paper provides an empirical demonstration for a practical approach of efficiency evaluation against the background of limited data availability in some regulated industries. Here, traditional DEA may result in a lack of discriminatory power when high numbers of variables but only limited...

Technical Efficiency and CO2 Reduction Potentials: An Analysis of the German Electricity Generating Sector

Seifert, Stefan; Cullmann, Astrid; Hirschhausen, … - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2014

In this paper, we analyze the technical efficiency of CO2 reduction potentials of German power and heat plants, using a non-parametric sequential Data Envelopment Analysis. We apply a metafrontier framework to evaluate plant-level efficiencies in the transformation of inputs into desirable...

Individual Well-Being in a Dynamic Perspective

D'Ambrosio, Conchita; Frick, Joachim R. - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2007

This paper explores the determinants of individual well-being as measured by self-reported levels of satisfaction with income. Making full use of the panel data nature of the German Socio-Economic Panel, we provide empirical evidence for well-being depending on absolute and on relative levels of...
